Patented May 14, 1935 UNITED STATES 1 Claim;

This invention relates to miniature or toy boats such as are adapted to be made from sheet metal, and refers more particularly to the construction of the hull which, as designed, is made from a single sheet of thin metal such as tin, copper or the like.

The purpose of the invention is to improve upon that class of invention disclosed in my prior Patent #1,673,701, dated June 12, 1929, and as before stated is directed to the construction of the hull proper. It is obviously adapted to different designs of toy boats, irrespective of the particular form of motor or means, if any, for propelling the boat.

The object of this invention is to provide a for the attachment of the deck member to the top edge of the hull. This deck may be in the form of a single plain flat deck, as shown in the present embodiment, or may include a main deck and a superstructure or double deck.

Since my present invention relates specifically to the formation of a hull of a boat, irrespective of the propelling mechanism employed, I have herein purposely omitted illustrating and describing any form of motor and means of supporting the same.

With the above objects in view, I have shown in the accompanying drawing a suitable embodiment of my invention, though it will be understood that the same is susceptible of such slight modifications as may come within the scope of the claim.

In the drawing Fig. 1 shows a perspective view of a deckcovered hull of a small toy boat, formed of sheet metal and constructed in accordance with my invention;

Fig. 2 shows a plan View of the said boat, portions of the deck of the stern and bow being broken away, better to show the construction of the corner portions of the stern and the seam of the bow;

Fig. 3 shows a plan view of a portion of a sheet metal blank from which the stern of the boat is formed;

Fig. 4 shows a perspective view illustrating the inside of the stern of the hull, before the deck member has been applied; and

Fig. 5 shows a detailed cross section, taken on line 55 of Fig. 2.

From the description to follow, it willbe seen that the boat, as shown in Figs. 1 and 2, is made of but two members, the hull being formed of one piece and the deck of another. The'hull is drawn and formed in such'a way as tomake it possible to produce a relatively deeper hull than was possible in the old way by a simple drawing process. This is particularly true whereit is necessary to form not only a relatively deep stern, but one having a substantially straight vertical stern end portion.

Referring in detail to the characters of reference marked upon the drawing, 8 indicates the hull, by which I mean the entire lower portion of the boat illustrated in the drawing, and 9 represents the deck which is the flat top member whose edges It are turned over and under the outwardly turned edges H disposed outwardly from the sides and back of the hull in .a way to form an absolute water-tight joint.

tral longitudinal depressed keel-like portion l3.-'

The upwardly bent portions of the blank i l which form the sides l5 of the hull are brought together to form a sharp bow where a seam it is employed for uniting theforward ends of the two said side portions by turning one of the said edges ll around and upon the other edge l8 and swedging them tightly together, as shown at It in Fig. 2.

Referring now more particularly to Figs. 3 and 4, it will be seen that in the formation of the straight deep back end member or stern, I first bend the two side edge portions l9l9 of the blank [4 along the dotted lines 2ll-2il and then fold in the corner portions 2l-2l along the dotted lines 22, 23 and 24, andsimultaneously therewith fold up the back end portion 26 along the dotted line 2?. This, as you will see, is done in a way to bring the folded corner portions 28-48 fiat against the inner face of the vertical stern end, whereupon the. hull is put into a suitable press where a blow is struck sufficient to flatten the folded portions and to tightly press them togetheragainst the back and form neatly finished corners of the hull, making it absolutely water-tight.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

turned down under and swedged to the angular ly disposed edges of the sides and back, the

stern having a back formed at a right angle to the sides and bottom and having corner portions that are formed by folding in the corner portions of the sheet metal blank from which the hull is formed, and disposed flat against the inner wall of the stern portion of the boat.
